IMPROVEMENT IN FASTENINGS FOR WlNDOW-BLINDS.

To all whom it may concern:

Be it known that I, ISAAC AMOS, of Bel Air, in the county of Harford andState of Maryland have invented certain new Improvements in Fasteningsfor Window-Blinds and Ido hereby declare that the following is a full,clear, and one act description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawing forming part of this specification.

The invention relates to improvements in the class of shutter orblind-hinges wherein a pintle is arranged to lock the same so as to holdthe shutter or blind open. The invention consists in providing thepintle with a finger-hold and in constructing and arranging it inconnection with the leaves of the hinge, as hereinafter described,whereby the shutter or blind may be closed after being unlocked withoutnecessity of taking hold of the same.

Figure 1 is a horizontal section exhibiting my invention when applied tothe blind. Fig. 2 is a view of the hinge exhibiting its appearance whenthe blind is thrown back and the leaves locked together.

A A represent the ordinary wings or leaves of a hinge, and a a theirrespective eyes. Each of these eyes is correspondingly slotted at a" a,so as to register, as shown in Fig. 2 of drawing. B is the pintle of thehinge, provided with a stud, b, near or about the middle, and with afingerhold, I), at the top.

The mode of operation is as follows: In Fig. 2 of drawing the pintle Bhas been pushed down until its stud rests in the slots a a of both eyesa a. Hence it is firmly locked and cannot be shaken out by the wind orany orc'linary cause. By seizing the fin ger-hold 7) between the thumband forefinger lifting it up and pressing from the window, not only isthe blind unlocked, but brought round and closed without the necessityof stretching any part of the person of the operator outside of thewindow. Again, when it is desired to lock the blind back it is onlynecessary to seize the finger-hold I) pull toward the window until theblind swings back, and press down on the pintle, then the blind will besecured firmly, as shown in Fig. 2.

Having thus fully described all that is neces sary to a fullunderstanding of my invention, what I desire to secure by LettersPatent, is-

The pintle B, provided with the finger-hold b and stud b, and combinedwith the leaves A A, having notches, as specified, whereby the pintlemay be operated to unlock and swing the shutter, as set forth.

To the above specification of my invention 1 have signed my hand this10th day of October, A. 1). 187 1.

ISAAC AMOS.
